please tell me how to randomize characters or words in C.
Example:
I will input R(red) Y(yellow) G(green) B(blue).
The computer will randomize it and it can also be duplicated.
for instance, it could be R R B G or G B B Y..

please tell me how.. I need it to make a game called MASTERMIND.

Help would be much appreciated. Thanks.

Solution 2

You may store the charachters in an array, e.g.

const char col[]={'R','Y','G','B'};

then use the rand function to select the index of the character:

int r = rand() % sizeof(col);

For instance:

int i;
for (i=0; i<4; i++)
{
  int r = rand() % sizeof(col);
  printf("%c ", col[r]);
}
printf("\n");

Sir, I have tried you're suggestion. But everytime i'm running the program. The set of code is always the same:

My code is like this:

const char col[]={'R','Y','BG','B','P','G'}; /*in the declaration area*/

for(i=0;i<6;i++) //IN THE
{
int r=rand()%sizeof(col); MAIN
printf("%c ",col[r]);
}
printf("
"); AREA//

THE OUTPUT IS ALWAYS: P P B P P Y

How to randomize it every time I would run the program?
Hope you can answer me back. Thanks.

To generate a different sequence every time your application runs, you have to call first 'srand( (unsigned)time( NULL ) );', see the example at the MSDN page http://msdn.microsoft.com/en-us/library/398ax69y%28VS.71%29.aspx
